What is cross-contamination?

Cross-contamination refers specifically to the transfer of harmful microorganisms or pathogens from one food item or surface to another, which can lead to foodborne illnesses. This often occurs when raw foods, especially meat, poultry, and seafood, come into contact with ready-to-eat foods, surfaces, or utensils that are not properly cleaned.

Understanding cross-contamination is crucial in food safety practices, as it highlights the importance of proper food handling, storage, and preparation methods to prevent the spread of pathogens. For instance, using separate cutting boards for raw meats and vegetables or ensuring that utensils are sanitized between uses are effective strategies to mitigate the risks associated with cross-contamination.

This concept is vital because foodborne diseases can cause serious health issues, making it essential for food handlers to be aware of how to avoid cross-contamination in all stages of food service and preparation.
